Searching Hints and Tips
The search engine can accept different types of search criteria as a query. The simplest is a single word or group of words. In this case the result will be articles that contain one or more of those words, ranked by the number of 'hits' for each word. The search is not case-sensitive.
The text search engine allows queries to be formed from arbitrary Boolean expressions containing the keywords AND, OR, and NOT, and grouped with parentheses. For example:
- diabetes cholesterol
- finds documents containing 'diabetes' or 'cholesterol'
- diabetes or cholesterol
- finds documents containing 'diabetes' or 'cholesterol'
- diabetes and cholesterol
- finds documents containing both 'diabetes' and 'cholesterol'
- diabetes not cholesterol
- finds documents containing 'diabetes' but not 'cholesterol'
- hypo*
- finds documents containing words starting with 'hypo'
